"President Obama will announce his intention to limit greenhouse gas emissions from existing power plants, increase appliance efficiency standards and promote renewable energy development on public lands in a speech Tuesday outlining his plan to use executive powers to address climate change."

"While the president has talked about the need to address global warming, using sweeping rhetoric in his second inaugural address to suggest it ranks as one of his highest priorities, he has been largely silent on how he intends to tackle the problem. In the speech at Georgetown University, according to individuals briefed on the matter who asked not to be identified because the plan was not yet public, Obama will detail a government-wide plan to not only reduce the nation’s carbon output but also prepare the United States for the near-term impacts of global warming.

They said those measures would include programs to enhance the resilience of coastal communities as well as Agriculture Department “climate adaptation hubs” that could help farmers cope with changes in temperature and precipitation."
